220A DC prekida\u010d strujnog kruga obavlja jedan posao koji va\u0161 BMS ne mo\u017ee samostalno: pru\u017ea vam fizi\u010dki prekid u krugu.<\/strong> Va\u0161 BMS \u0161titi \u0107elije od prekomjerne struje i kratkih spojeva, ali kada trebate raditi na paketu, izolirati inverter ili isklju\u010diti napajanje u hitnom slu\u010daju, trebate ne\u0161to \u0161to zapravo mo\u017eete isklju\u010diti. Ovaj 2-polni DC prekida\u010d smje\u0161ten je izme\u0111u va\u0161e baterije i invertera, dodaje za\u0161titu od kratkog spoja uz BMS i daje vam vidljivu to\u010dku za isklju\u010divanje.<\/p>

Za\u0161to 220A DC prekida\u010d strujnog kruga nadma\u0161uje oslanjanje samo na BMS<\/h3>

BMS je za\u0161titni ure\u0111aj, a ne prekida\u010d. On \u0107e prekinuti struju kada ne\u0161to po\u0111e po zlu, ali ne\u0107e vam omogu\u0107iti da izolirate paket po potrebi \u2014 i ne\u0107e o\u010distiti \u010dvrsti kratki spoj na glavnom DC napajanju kao \u0161to to prekida\u010d mo\u017ee. Dodavanje prekida\u010da daje vam tri stvari koje sam BMS ne mo\u017ee:<\/p>

  • Ru\u010dni prekid<\/strong> za odr\u017eavanje, nadogradnje i hitne slu\u010dajeve<\/li>
  • \u010ci\u0161\u0107enje kratkog spoja<\/strong> ocijenjeno na 7,5kA<\/li>
  • Kvar koji mo\u017eete vidjeti<\/strong> \u2014 isko\u010deni prekida\u010d pokazuje da se ne\u0161to dogodilo, umjesto da vas ostavlja u neizvjesnosti<\/li><\/ul>

    AC prekida\u010di ne pripadaju na krug baterije<\/h4>

    Ovo je najva\u017enija pogre\u0161ka. Naizmjeni\u010dna struja prolazi kroz nulu 50-60 puta u sekundi, a taj prolaz kroz nulu omogu\u0107uje AC prekida\u010du da ugasi luk kada isko\u010di. Istosmjerna struja nema prolaz kroz nulu, pa luk nastavlja gorjeti. AC prekida\u010d mo\u017ee zakazati u \u010di\u0161\u0107enju kvara na baterijskom sustavu, \u0161to je upravo situacija koju prekida\u010d treba rije\u0161iti.<\/p>

    \u0160to ocjena 220A zna\u010di u praksi<\/h3>

    Naj\u010de\u0161\u0107a konfiguracija u DIY skladi\u0161nom paketu je 200A BMS. Ovaj prekida\u010d je ocijenjen na 220A, korak iznad toga, \u0161to vam daje marginu za ulaznu struju bez prevelikog dimenzioniranja ure\u0111aja ili kabela.<\/p>

    Jedno pravilo koje je va\u017enije od tablice: nikada ne ugra\u0111ujte prekida\u010d ocijenjen ispod kontinuirane struje va\u0161eg sustava i nikada ne ugra\u0111ujte kabel ocijenjen ispod prekida\u010da.<\/p>

    Fitting a DC Circuit Breaker Into a DIY Battery Box<\/h3>

    At 78 \u00d7 38 \u00d7 63mm and 225g, this breaker fits inside a battery enclosure or a tight cabinet instead of needing its own panel.<\/p>

    1. Mount it where you can reach it.<\/strong> A breaker you cannot access is decoration.<\/li>
    2. Follow the LINE and LOAD markings<\/strong>, and confirm the wiring diagram in the manual before connecting.<\/li>
    3. Torque the terminals to spec<\/strong> and re-check after the first thermal cycle.<\/li>
    4. Keep AC and DC separate.<\/strong> This device goes on the DC side between battery and inverter.<\/li>
    5. Leave room for the cables.<\/strong> Thick DC cable needs bend radius.<\/li><\/ol>
